Answer:
So the answer is just 7
Step-by-step explanation:
Let's do the number first.
21/3 = 7 so the answer will contain a 7.
I wonder what the best way to do e^3 is. Here' one way.
e^3 / e^3 = 1 which is just the answer. but suppose e = 5
Then you have (5*5*5)/(5*5*5) = 125/125
anything divided by itself = 1
so 125/125 = 1
A third way you could do it is like this
e^3/e^3 = e^3 * e- 3
Rule when you move anything (except zero) up from the denominator up to the numerator the power becomes the opposite of what it was.
Rule 1a: when you move anything (except 0) down to the denominator from the numerator the sign becomes the opposite to what it was.
Now you can add the powers
e^(3 - 3) = e^0 = 1

Answer:
Probability = 2/13 ≈ 15.4%
Step-by-step explanation:
We are looking for probability of drawing an ace or king from a standard deck of cards.
In a standard deck of cards, there are <em>4 ace and 4 king</em>.
4 + 4 = <u>8</u>, this is the number of possible "correct" cards you can draw, which satisfy the conditions.
Since a standard deck has <em>52 cards</em>, this is the number of cards you can draw, the "possible outcomes".
Probability is the <u>number of "correct" outcomes divided by the total possible outcomes</u>.
The probability is 8 / 52, but we need to <u>reduce the fraction</u>.
Both numerator and denominator are divisible by 4.
8 / 52 = 2 / 13
If you want the probability as a percentage, divide 2 by 13 and multiply by 100.
Probability = 2/13 ≈ 15.4%
The domaine of a functions is the set of the values wherein the function is defined, or the set of the values that the function may take. The range is the image of the function.
Answer A is correct.
C and D are correct too by the definition of the inverse functions.
F is a correct answer.
